It is an elastic member that urges to rotate in the opening direction.

  FIG. 3 is a perspective view showing a state when the battery lid unit 20 is attached to the device housing 1.

  2 and 3, the operation when attaching the battery lid unit 20 to the device housing 1 is carried out with the battery lid unit 20 opened at an angle that is substantially perpendicular to the device housing 1. 21a is fitted to one bearing portion (not shown) of the device casing 1. Further, the shaft operating portion 23b is held while being slid, and the movable shaft 23a is retracted inside the lid body 21, and the movable shaft 23a side is the other bearing of the device housing 1 with the fixed shaft 21a of the lid body 21 as a fulcrum. Rotate to the position where it fits with the part 1b. Furthermore, the holding | maintenance of the shaft operation part 23b is cancelled | released, the movable shaft 23a is protruded, and it is made to fit in the other bearing part 1b. The operation for removing the battery lid unit 20 from the device housing 1 is the reverse of the above procedure.

  Next, the operation of the urging spring 25 accompanying the operation of the slide shaft 23 when the battery lid unit 20 is attached to the device housing 1 will be described with reference to FIGS. 4 and 5.

  4A and 4B are diagrams showing the configuration of the battery lid unit 20 in a state in which the movable shaft 23a of the slide shaft 23 protrudes. FIG. 4A is a front view, FIG. 4B is a bottom view, and FIG. It is a right view. 5 is a diagram showing the configuration of the battery lid unit 20 in a state in which the movable shaft 23a of the slide shaft 23 is retracted, where (a) is a front view, (b) is a bottom view, and (c). These are right side views.

  4 and 5, the lid body 21 of the battery lid unit 20 is provided with a cam portion 21b with which the protruding portion 25c of the urging spring 25 abuts. The protrusion 25c of the urging spring 25 abuts on the cam portion 21b of the lid body 21 by being twisted and urged counterclockwise in FIGS. 4 (c) and 5 (c). In a state where the movable shaft 23 a of the slide shaft 23 protrudes from the lid body 21, the protruding portion 25 c of the biasing spring 25 is in contact with the position 21 c of the cam portion 21 b of the lid body 21. As shown in FIG. 4C, the protruding portion 25c of the urging spring 25 protrudes downward substantially parallel to the planar direction of the battery lid unit 20.

  When the shaft operating portion 23b of the slide shaft 23 is operated rightward in FIG. 4A to retract the movable shaft 23a inside the lid body 21, the biasing spring 25 protrudes as the slide shaft 23 moves in thrust. The part 25c also moves to the right as shown in FIG. Since the protruding portion 25c of the biasing spring 25 moves in contact with the cam portion 21b of the lid main body 21, the protruding spring 25 protrudes when the movable shaft 23a of the slide shaft 23 is retracted inside the lid main body 21. The part 25c is in contact with the position 21d of the cam part 21b. Thereby, as shown in FIG.5 (c), the protrusion direction of the protrusion part 25c of the urging | biasing spring 25 moves to a right rotation direction.

  That is, when the battery cover unit 20 is attached to the device housing 1, if the movable shaft 23 a of the slide shaft 23 is retracted inside the cover body 21, the position of the protrusion 25 c of the biasing spring 25 is interlocked with the retract. Changes. When the battery lid unit 20 is attached to the device housing 1, the opening angle of the battery lid unit 20 with respect to the device housing 1 is about 120 ° when the protrusion 25 c of the biasing spring 25 is in the position shown in FIG. 4. The biasing force in the opening direction by the biasing spring 25 acts to the position. Therefore, the rotation range of the battery cover unit 20 is about 120 °, and the rotation range in which the biasing spring 25 urges the battery cover unit 20 is about 120 °.

  On the other hand, when the battery lid unit 20 is attached to the device housing 1, when the protrusion 25c of the urging spring 25 is in the position shown in FIG. The urging force in the opening direction by the urging spring 25 is applied to the position. When attaching the battery lid unit 20 to the device housing 1, the battery lid unit 20 is attached to the device housing 1 at a position where the opening angle of the battery lid unit 20 with respect to the device housing 1 is about 90 °. Therefore, the rotation range of the battery cover unit 20 is about 120 °, and the rotation range in which the biasing spring 25 urges the battery cover unit 20 is about 90 °.

  By doing so, the protruding portion 25c of the biasing spring 25 traces the cam portion 21b by operating the shaft operating portion 23b, so that the battery lid unit 20 is moved by the biasing spring 25 within the rotation range of the battery lid unit 20. The range of biasing in the opening direction becomes smaller. As a result, when the battery lid unit 20 is attached to the device housing 1, the battery lid unit 20 can be attached to the device housing 1 without charging the urging spring 25 or only by slightly charging it. .

  FIG. 6 is a cross-sectional view showing a state in which the battery lid unit 20 is opened to the vicinity of the contact position in the opening direction.

  In FIG. 6, in a state where the battery lid unit 20 is attached to the device housing 1, the protruding portion 25 c of the urging spring 25 is the lid body in the vicinity of the opening angle (butting position) in the opening direction of the battery lid unit 20. 21 is set so as to abut against the cam portion 21b. That is, the protrusion 25c of the biasing spring 25 does not hit the cam portion 21b of the lid body 21 until it reaches the contact angle 1a of the device casing 1 until it reaches the vicinity of the contact angle in the opening direction of the battery lid unit 20. When it comes into contact and reaches the vicinity of the contact angle, it hits the cam portion 21b.

  Thus, the biasing force in the opening direction of the battery lid unit 20 by the biasing spring 25 can be applied until the vicinity of the contact angle in the opening direction of the battery lid unit 20 is reached. The abutment angle (abutment position) in the opening direction of the battery lid unit 20 is a state in which the battery lid unit 20 blocks the battery housing portion when the battery lid unit 20 is rotated to the maximum in the opening direction. The angle (position) from (closed state).

  According to the above configuration, in the battery lid unit 20 that can be attached to and detached from the device housing 1, as described above, the battery lid unit 20 is attached to the position of the contact angle in the opening direction (about 120 ° in the present embodiment). The biasing force in the opening direction by the biasing spring 25 acts. At this time, when the shaft operating portion 23b is operated, the protruding portion 25c of the urging spring 25 traces the cam portion 21b, whereby the angle range in which the urging spring 25 applies the urging force is narrowed to about 90 °. Therefore, since the biasing force of the biasing spring 25 does not act when the opening angle of the battery lid unit 20 is between 90 ° and 120 °, it is easy to remove the battery lid unit 20 when removing it from the device housing 1. Thereby, it is possible to configure a detachable battery lid unit 20 holding mechanism that has good battery attachment / detachment operability and excellent attachment workability.

  Further, a protruding portion 25c is formed integrally with the urging spring 25, and the battery lid unit 20 is urged to rotate in the opening direction by an urging force generated by torsion of the coil portion 25d of the urging spring 25. Further, a cam portion 21b for moving the protruding portion 25c of the urging spring 25 in a direction in which it does not abut against the abutting portion 1a on the device casing 1 side is provided on the lid main body 21 constituting the battery lid unit 20. Forming. With this configuration, a mechanism that urges the battery lid unit 20 to rotate in the opening direction and a mechanism that moves the protruding portion 25c of the urging spring 25 in a non-contact state can be realized without adding any components. . Thereby, the holding | maintenance mechanism of the battery cover unit 20 excellent in operativity can be comprised small and lightweight and cheaply.

  As described above in detail, according to the present embodiment, the battery housing portion of the device housing is configured to be detachable and openable / closable from the device housing and is biased in the opening direction. The urging force in the opening direction acts to the opening position where the battery can be favorably attached and detached. Thereby, it becomes possible to improve the workability of attaching the battery lid unit to the device housing. In addition, the operability of the battery lid unit when opening and closing the battery lid unit can be improved.
